The Big Apple would become a Walmart city if local shoppers had their way.

A poll of 1,000 New Yorkers found that a whopping 71 percent favor locating a Walmart store in the city, with only 24 percent opposed.

And the survey — conducted by pollster Douglas Schoen for the mega-retailer — also showed that 63 percent gave a thumbs-up to having a Walmart located in their neighborhood, with only 34 percent opposed.

In general, two-thirds of city residents had a favorable opinion of Walmart.

The nation’s largest big-box retailer currently does not have a store anywhere in town — mostly because of fierce opposition from labor leaders and the union-supporting City Council.

But the non-union company — which has stores in the surrounding suburbs — is waging an ambitious marketing campaign to establish a presence here.

It has proposed using unionized construction workers to build its store, but said it would not change its policy toward employees, sources said.

The Arkansas-based business is scouring the five boroughs for a location, eyeing the Gateway Shopping Center in East New York, Brooklyn.

The survey’s pro-Walmart findings could be a game-changer in bolstering its effort.

“We are encouraged by the overwhelming level of support for bringing Walmart to New York City,” said company spokesman Steven Restivo.

The results should certainly send shivers down the spine of New York’s anti-Walmart political establishment.

The strongest support for Walmart came from city residents that unions and politicians claim to represent — poor and working-class minorities: 81 percent of blacks and 77 percent of Hispanics endorsed the retailer setting up shop here. So did 73 percent of Asians and 64 percent of whites.

The positive views toward Walmart also crossed geographical, age and income demographics.

And two-thirds oppose the City Council attempting to pass a law to block Walmart.

Of those who support Walmart, about half said its stores would create new jobs, and provide more consumer choices and low-cost products. Nearly a third said Walmart would make shopping more convenient, and a quarter said they would save money.

“It’s almost a no-brainer,” said Schoen, a consultant who has conducted surveys for Bill Clinton and Mayor Bloomberg. “This is a deal that benefits everyone — and poor and working-class people benefit the most. It’s a rational act.”

Of the one-quarter of respondents opposed to Walmart, about half said they believe the retailer offers workers low wages and poor benefits; 43 percent said it hurts mom-and-pop businesses; more than a quarter objected to hiring non-union workers; and 14 percent said it would increase traffic congestion.
